141540-63-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 141540-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,5,4 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141540-63:
(8*1)+(7*4)+(6*1)+(5*5)+(4*4)+(3*0)+(2*6)+(1*3)=98
98 % 10 = 8
So 141540-63-8 is a valid CAS Registry Number.

New non-proteogenic aminoacids bearing an enol aryl-ether moiety

Daumas,Vo-Quang,Le Goffic

, p. 2373 - 2384 (2007/10/02)

Aminoacids bearing an enol aryl-ether moiety have been synthesized by a new method allowing a great versatility in the introduction of N-protective groups and enol ether functions. This method involves a Wittig-Horner condensation affording alpha, beta-dehydrohomoserine ether derivatives, followed by a regio and stereoselective isomerization into the desired E enol ether. Clean deprotection was achieved providing new 2-amino-4-aryloxybut-3(E)-enoic acids 3.
